25 Oct 2011 The shape of our manually tunable condenser lens can be adapted from flat to strongly convex by rotating an adjustment ring.
A tunable condenser lens is the ideal choice for illumination systems based on LEDs. In combination with an LED lens (TIR lens) large illumination angle variations can be achieved while maintaining an excellent spot quality and a very high optical efficiency. The low-dispersion lens material prevents color errors from spoiling the spot quality. |
